COTTON-PACKER.

Specification of Letters Patent. P t t y 27 -1 5 Application filed July 24, 1914. Serial No. 852,883.

To all whom it may concern: I

Be it lmown that I, RANDOLPH L. WRIGHT, a citizen of the United States of America, and resident of W edgefield, in the county of Sumter and State of South Carolina have invented certain new and useful Improvements in Cotton-Packers, of which the following is a specification.

This invention relates to presses and par.- ticularly to cotton baling machines.

An object of this invention is to provide means for tamping cotton lint so as to compress it in the presser boxes of a baling machine, the said invention being designed to accomplish the results which at the present time are accomplished by tramping on the cotton as it is delivered to the said molds or.

hoppers.

Furthermore, an object of the present invention is to provide novel means fortamping the lint as it is deliveredto the presser boxes, thus causing a slight compression of the particles of lint as they are delivered rather than topress the same after a bulk of material has been delivered to the presser box, it having been found that the continuous tamping operation, due to the jarring action and the weight of the compressing member so condenses the lint as to enable the production of relatively heavy bales, as

compared with their size and since this is accomplished by mechanical means of novel construction, the rapidity of action and the efiiciency of action is verymarked as compared with methods now in common use.

A still further object of this invention is to provide a tamping machine having novel means for elevating the-tamping member, novel means beingalsoprovided for releasing the said tamping member and a still further object of the invention is to provide novel means for oscillating a guide or frame for thetamping memberto change the position of its stroke or the rotation of the stroke upon each elevation or descent of the said tamping member.

A still further object of this invention is to provide means for holding the tamping member inactive while the molds or boxes are being removed or replaced, and the said invention furthermore eontemplates'the provision of novel means for tripping the said tamping member so that it maybe released from its elevating means and permitted to fall by gravity.

A still further object of this 1nvent1on is erence will be had to the accompanying drawings forming part of this specification wherein like characters denote correspondmg parts in the several views, and in which Figure 1 illustrates a view in end elevatlon of the cotton tamper embodying the invention; Fig. 2 illustrates a side elevation thereof; Fig. 3 illustrates a sectional view on the line 3-3 of Fig. 2; Fig. 4 illustrates an enlarged detail view of the tamperand the wheel for elevating the same; Fig. 5 illustrates a top plan view of the tamper and the elevating wheel; Fig. 6 illustrates a detail sectional view of a fragment of the tamper and one of the guidesyFig. 7 illustrates a face view of the cam; Fig. 8 illustratesa sectional view of the cam on the,

line 88 of Fig. 7 Fig.9 illustrates an enlarged detail view of the pitman withthe roller adapted towork in the cam groove; and FigwlO illustrates an enlarged detail 'view of the latch for holding the tamper elevated.

In these drawings. 15 denotes a suitable frame. including the uprights 16 and. 17, near the upper ends of. each are the pintles 18 on which the guides 19 are oscillatingly mounted. The guides may be of'any construction but are hereshown as consisting of bars of material having grooves 20 which receive thetongues 21 extending longitudinally in the edges of the tamper 22, thus the said tamper is guided vertically and is carried from side to side as the guides are 0scillated. The guides 19 are connected by a yoke 23 which yoke terminatesin an arm 24:. A link 25 is pivoted to the arm 24 and said link carries a roller 25 mounted on a pin 25 and said roller enters the cam slot 26 in the cam wheel 27, which cam wheel 27 is secured toa power shaft 28 such as is em- :ployed under the floors of gins as they are commonly constructed. The rotation of the cam Wheel, therefore, oscillates the guides its and causes the tamper 2 2 to descend into the presser boxes 29 near the side walls thereof,

that is to say, it descends near the side wall at one operation and at the opposite side wall at the next operation and thereby compresses or condenses the lint uniformly throughout the area of the said presser box 29.

The tamper 22 is preferably of metal and has at one side a series of ribs 30 which ribs may be integral with the tamper or they may be rods inserted or secured'to the tamper in any appropriate way. As a means for elevating the tamper, a Wheel 31 is mounted on a shaft 32, the said shaft 32 having a pulley 33 with a belt 34. The belt is driven from the power shaft of the gin through any type of power transmitting means, those shown in the drawings being suflicient for the purpose of illustrating one embodiment of the invention, it being obvious that the power transmitting meansmay be modified to suit particular requirements. The wheel 31 is seen to have a series of teeth 35 which project between the ribs 30 and on the upward movement of the said teeth, they engage the ribs and communicate motion to the tamper. The shaft 32 is journaled in a swinging frame 36, the said frame having its upper end pivoted to the stationary frame and being oscillatable'with relation to the said stationary frame and with relation to the tamper, so that when the oscillating or swinging frame is moved away from the tamper, the teeth of the wheel 31 are disengaged from the" ribs of the tamper, thus permitting the said tamper to descend by gravity and tamp the contents of the presser boxes. The swinging frame has a handle 37 by which the frame may move away from or toward the tamper and provision is also made for oscillatingly swinging the frame automatically by a cam 38 which is carried by the tamper and contacts with the said frame as the tamper is elevated, thus causing the said cam to force the swinging frame away from the tamper to such an extent as to disengage the teeth of the wheel from the ribs of the tamper. This operation will cause a release of the tamper and permit it to descend by gravity in the same manner as the device would operate "should the swinging frame be manipulated by hand.

Provision is made for holding the tamper in an elevated position when it is desired to change the boxes or presser boxes and to this end the upper end of the tamper has a lug 39 adapted to enter a clamp or clasp 4L0 "suspended from the frame.

The clasp 4-0 consists of two coacting jaws pivoted so that they approach each other or recede,the

Copies of this patent may be obtained for the tamper elevated or that they may be forced apart by the lever 41 to release the lug and consequently the tamper, when assumption of the operation is to be had. The lever for operating the clips or clasps is actuated by a rod extending near the floor where it may be grasped by an operator. The lower ends of the tamper guides are slotted to receive the plates 42 and the said plates 42 constitute brackets held by the uprights 16 and 17. As the guides oscillate, theirlower ends are guided by the brackets. As the functions of the several elements of the device have been described in connection with a disclosure of the elements themselves, a detailed description of the operation will, it is thought, be unnecessary.

1.'In-a cotton lint tamper, a frame, a guide oscillatingly supported thereby, a tamper adapted to reciprocate in the guides, means for elevating the tamper, and means whereby the elevating means is caused to release the tamper, and means for oscillating the guides.

2. In a cotton lint tamper, a frame, guides oscillatingly mounted on the frame, a tamper engaged by theguides, means for elevating thetamper, means for causing a release of the'tamper-by the elevating means, whereby the tamper is allowed to fall by gravity, means for oscillating the guides, and means for holding the tamper-inoperative.

3. In a cotton lint tamper, a frame, guides oscillatingly mounted on the frame, a tamper engaged by the guides, means for ele per, oscillating guides for the tamper, means for oscillating the guide, a swinging frame, a tamper elevating wheel carried by the frame, means for rotating the elevating means, and meansfor swinging the frame away from the tamper whereby the tamper elevating wheel releases the tamper.

In testimony whereof, I affix my signature in the presence of two witnesses.
